Abstract

<P>PROBLEM TO BE SOLVED: To enable a reverse control for a train to be realized in an ATACS when a train has passed over a stop indicator along a platform or the like. <P>SOLUTION: When the train 1 has passed the station stopping position target 5, and after being stopped by using the brake, a driving switch 15 is switched to the reverse side, the fact is notified to a ground side controller 16 together with the positional information of the train. The ground controller 16 prepares attribute information including a stopping limit position at the time of reversing to the platform 4, and positional information of a following train, and transmits them to the train 1. The stopping limit position information indicates the position of a branching point 6. An onboard controller 10 prepares a security braking pattern signal 19 for the rear side from those information. When the train 1 is reverse-driven, if the train 1 approaches the following train or the branching point 6, braking is automatically applied by the security braking pattern signal 19, and the train 1 stops. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a train retreat control method and system used when a train is retreated when the train passes a stop position target in a station platform or the like.

  Conventionally, when a train tries to stop at a station platform, if the train passes a predetermined stop position target due to a delay in the brake operation of the driver, the driver switches the operation switch back (back) and While moving backward, the brake is stopped manually by applying the brake at the stop position target. For example, Patent Document 1 has been proposed as a countermeasure when a train passes a stop position target.

  On the other hand, in conventional railroads, the train operation line is divided into several sections and managed so that only one train can enter each section, thereby preventing train collision. For this reason, each section is provided with a track circuit that detects the presence or absence of a train by short-circuiting the rails by the train axle.

Recently, a train control system called Advanced Train Administration and Communications System (ATACS) is being researched and developed. In ATACS, the train itself detects the position of the train, which was conventionally done by the track circuit. The on-board controller is installed on the train and the ground controller is installed on the ground. Reads the ID of the ground unit installed for each predetermined section along the track, calculates the travel distance from the point by integrating the speed with the speedometer, always detects the current position of the train, the position information on the ground Send to control device. Based on this position information, the ground control device transmits the position information of the preceding train and information indicating the stop limit based on the route to the on-board control device. The on-board controller creates a brake pattern signal based on the received information and performs brake control. As shown in FIG. 3, the brake pattern signal is a pattern signal indicating a speed control characteristic with the travel distance l (or time) on the horizontal axis and the speed v on the vertical axis, and automatically when the train approaches the preceding train. The brake can be applied to avoid collision. According to such ATACS, cost can be reduced and safety can be improved compared to conventional train control using a track circuit, and transportation efficiency can be improved by performing appropriate interval control. .

In the above-mentioned reverse control method by manual operation of the driver, the platform length, the branch point of the track, the position of the railroad crossing, etc. are different for each station. Also, it is difficult to notice the following train. For this reason, there has been a problem in safety, such as accidentally passing a branch point at the rear and causing derailment or the like, and there is a risk of collision between trains.
It is an object of the present invention to make it possible to implement a reverse control of a train in a home or the like by using an ATACS and improve safety.

  The train retreat control method according to the present invention detects the ID of a ground element arranged for each predetermined section along the track, calculates the travel distance by integrating the train speed from this detection point, and calculating the travel distance. A train reverse control method used in a train control system that detects a position, obtains attribute information about the section based on the position information, and controls the operation of the train based on the attribute information. When the forward / reverse switch is switched to reverse because the vehicle has passed the stop target position, it automatically stops when traveling to the reverse limit position based on the attribute information of the section including the stop target position. A brake control signal is generated.

  The train reverse control system according to the present invention divides the track on which the train travels into a plurality of sections, stores the attribute information of each section, and the ID of the ground unit arranged for each predetermined section along the track. The train position detecting means for detecting the position of the train by calculating the travel distance by adding the train speed from this detection point, and obtaining attribute information corresponding to the detected position from the storage means, When the attribute information includes a retreat limit position and the train starts retreating, a brake control signal for automatically stopping when the train retreats to the retreat limit position is created based on the attribute information, and the train Control means for performing brake control is provided.

  ADVANTAGE OF THE INVENTION According to this invention, the retreat control of a train when a train passes the station stop position target in a station platform etc. is realizable in ATACS. In addition, it is possible to automatically control the backward movement of the train safely and reliably without imposing a burden on the driver.

Hereinafter, an embodiment when the present invention is applied to ATACS will be described with reference to the drawings.
FIG. 2 is a system configuration diagram of a part related to the present invention of ATACS.
In FIG. 2, the line 2 of the route on which the train 1 travels is divided into a plurality of sections (blocks), and the section shown in FIG. 2 is a section including the platform 4 of the station. The ground control device 16 stores attribute information indicating the characteristics of each section.

  It is assumed that the train 1 enters the station platform 4 in the direction of the arrow 3 on the track 2 and stops at the station stop position target 5. In the illustrated example, in the line 2, the line 7 branches from the branch point 6 in front of the home 4, and the line 9 branches from the branch point 8 behind the home 4. The train 1 is equipped with an on-board controller 10, a track DB (database) 11 storing track data, a vehicle head 12, a radio device 13, and a speedometer 22, and the cab 14 is moved forward and forward. An operation switch 15 for switching back is provided. A ground control device 16 is installed on the ground, and a ground unit 17 having an ID of the section is installed at a predetermined position on the track 2.

  In the above-described configuration, the on-board control device 10 reads the ID of the ground unit 17 by the on-board unit 12 and obtains the map data of the track stored in the track DB 11 and the speed by the speedometer 22 based on this ID. The current position of the own train is obtained from the travel distance, and this position information is transmitted from the wireless device 13 to the ground control device 16. The ground control device 16 obtains the position information of the preceding train based on this position information, creates attribute information including the stop limit position for the platform 4 of this station, and transmits it to the train 1. In this case, the stop limit position information is information indicating the position of the branch point 8. The on-vehicle control device 10 creates a front safety brake pattern signal 18 based on these pieces of information. The security brake pattern signal 18 is the same as that shown in FIG.

  Here, it is assumed that the driver applied the brake to stop the train 1 at the station stop position target 5, but has gone too far. At this time, when approaching the position of the preceding train, the safety brake pattern signal 18 is activated and the brake is automatically applied to avoid a collision. Further, even when the train 1 approaches the position of the branch point 8, the brake can be automatically applied and stopped before the branch point 8 by the security brake pattern signal 18.

FIG. 1 is a block diagram showing an embodiment in which the present invention is applied to the ATACS of FIG. 2. Parts corresponding to those in FIG.
After the train 1 has passed the station stop position target 5 and the driver has braked and stopped, when the operation switch 15 of the cab 14 is switched from forward to backward, this is notified to the ground control device 16 together with the position information. Is done. In response to this, the ground control device 16 creates attribute information including the stop limit position when the home 4 moves backward and position information of the succeeding train, and transmits them to the train 1. The stop limit position information in this case is information indicating the position of the branch point 6. The on-vehicle controller 10 creates a rear safety brake pattern signal 19 based on these pieces of information. The safety brake pattern signal 19 is opposite to the front safety brake pattern signal 18.

  The driver causes the train 1 to retreat in the direction of the arrow 20 in order to stop at the station stop position target 5, but if the driver approaches the position of the succeeding train at this time, the safety brake pattern signal 19 works to automatically brake. It can take and avoid collisions. Further, even when the train 1 approaches the position of the branch point 6, the brake can be automatically applied and stopped before the branch point 6 by the security brake pattern signal 19.

The content of the attribute information of the section shown in FIG. 1 includes a section that includes a stop such as the home 4 and that is permitted to move backward.
Further, in the present embodiment, the position information of the train 1 detected by the vehicle upper element 12 is once transmitted to the ground control device 16, and attribute information is created on the ground control device 16 side and transmitted to the vehicle control device 10. The safety brake pattern signal is created, but by storing the attribute information in the track DB 11 of the on-board controller 10, the on-board controller 10 obtains the attribute information and creates the safety brake pattern signal 19. You may make it do.

According to the present embodiment, when the train 1 has passed the station stop position target 5 at the station platform or the like, the operation switch 15 is switched to the reverse direction so that the subsequent train, branch point, etc. Since the safety brake pattern signal 19 suitable for the situation is created, it is possible to prevent an accident such as the train 1 passing through the branch point 6 or a railroad crossing or a collision with the following train.
In addition, it is possible to control the reverse of the train safely without imposing any burden on the driver by effectively utilizing the ATACS facilities that are currently under development.
